The National Weather Service has issued a flood watch through Saturday morning for the majority of southern New England.

Rain will likely be heaviest along and south of the Massachusetts Turnpike, and 1 to 3 inches are expected. Because the ground is already heavily saturated from recent rains, rivers and streams may rise over their banks.

Residents who live in flood-prone areas or along riverbanks should be alert.

Thursday afternoon and evening commuters should be prepared for reduced visibility and flooded roadways.
